Your gearing isn't terrible, but it does look like you care a little to much about regen and not enough about throughput. I'd change your helm/shoulder chants from mp5 to the crit equivalent. You have a lot of SP/Spirit gems for 5 sp bonuses that probably just aren't worth it. Get the minimum amount of blue gems for your meta and then go crazy w/ SP/haste gems in all yellow/blue and even red sockets. At this level of gear, with shadowfiend and a mana pot you shouldn't have any trouble lasting through any current content. Add mana tide and/or innervate and mana stops being a concern.
This is all assuming that you play holy primarily, if you play disc primarily then you gem pure SP in all sockets. After getting your meta requirements, which I think is 2 reds anyway so yeah, all 23 SP. Bigger shields = better disc priest.
Your talents and glyphs are a bit more troubling.
Lets do disc first cause it's a bit more straightforward.
http://www.wowarmory.com/character-tale ... bz&group=1 Copy that, major glyphs included. I honestly don't know what you're trying to do w/ your disc spec. Renew and improved healing? Not taking aspiration? Mana is never a concern, even if you're spamming shield on every gcd, which is pretty much what you do. Aspiration basically means that you can do all your cool stuff more often, why you wouldn't want that is just weird. The only time I use renew as disc is on tanks, if you're using a gcd anywhere else it should be a shield or PoM. Not having PW:S glyph in your disc spec is just embarrassing and you should feel ashamed.
Healing as disc is easy. Shield everything. Keep PoM on CD. Need to heal something and it has weakened soul? Penance, then flash spam until Penance is off CD or weakened soul is off. Only Gheal if you have borrowed time and Penance is on CD. Sometimes you might have to think about who you shield, like if a ghost is near your melee on Lady Deathwhisper or if there's a green ooze on PP and your melee is chasing it. However, most fights you can probably just go up and down your raid frames and do just fine as a disc priest. If you want to be really good, make sure that you have a macro to give PI to a damage caster and use it on CD.
For holy, go here:
http://www.wowarmory.com/character-tale ... sia&group=You can decide if you really want BnS, he has it for a specific fight. If you run w/ a disc priest I probably wouldn't bother but if you don't have a disc priest then I'd grab it. Pretty much the best talent in WoW and is a mini game unto itself. Before I came to Vodka I played Holy primarily in a guild w/out a disc priest and with a few people slower to react and I saved more lives using BnS in one week than I did w/ GS in a month. You'll notice that kina is renew spec which is the way to go as holy. Why you have empowered healing, test of faith and prayer of healing glyph, but not emp renew and serendipity, I'm not going to speculate. However, just forget whatever you were doing before and learn to love renew. Renew like you would shield as disc. Keep PoM on CD, tanks are always a good choice for target, when a group of people take a decent amount of damage, use CoH, then flash whoever is lowest because you almost certainly just got a SoL proc. If you know that a decent amount of burst is gonna happen that you can plan for, then stack serendipity and time a PoH to land right after the damage, follow with an immediate CoH and SoL flash, then everyone's back at full health. So basically, keep PoM and CoH on CD, spam renew and use your SoL procs wisely.
Kina's welcome to come and tell me I'm retarded or whatever, but that should cover the basics. Remember that as a healer your job is to keep the raid alive. Don't worry about meters or anything like that, healing is wow is a win/lose scenario. Either your raid is alive and you win or your raid is dead and you lose, noone gives a fuck about your HPS if they're running back from the graveyard.
